Nateglinide Breastfeeding Warnings

Use is not recommended

Excreted into human milk: Unknown
Excreted into animal milk: Yes

Comments: If used, monitor blood glucose in the breastfed infant.

Due to lack of information on the use of this drug during lactation, an alternate drug may be preferred, especially in newborn or preterm infants. Studies in lactating rats have shown this drug is excreted into milk with a milk to plasma ratio of approximately 1:4. Some authorities do not feel it is a reason to discontinue breastfeeding if this drug is required by the mother. This drug is a weak acid and highly protein bound, therefore, it may not pass into breastmilk in clinically important amounts.
